What is YK-11?
YK-11 is a steroidal compound built from a dihydrotestosterone backbone, first described by Japanese researchers in 2011. It’s often grouped with SARMs, but it’s steroidal and only a partial agonist at the androgen receptor.
Its reported trait is raising follistatin levels in muscle cells, which ties it to myostatin research.

Research on YK-11
Kanno and colleagues showed in Biological and Pharmaceutical Bulletin (2013) that YK-11 drove muscle cell differentiation in C2C12 myoblasts more strongly than DHT and increased follistatin expression.
A 2018 study reported effects on osteoblast cells as well. There are no human trials.

How YK-11 gel packs work
Each gel pack is a sealed, single-use packet holding 20mg of YK-11. The gel is made for oral administration in research models. It isn’t a topical product, so it’s not meant to go on skin.
Because every packet holds the same amount, gel packs are an easy way to keep amounts identical across a study without weighing or measuring liquids. Packs come in 5, 10 or 30, so you can match the order to the length of your study.
Planning a study with YK-11 gel packs
Count one packet per administration, then add a few spare. Keep all the packets for one study from the same order so they share a batch.
YK-11 quality and testing
Every batch of YK-11 is checked with liquid chromatography-mass spectrometry (LC-MS) before it goes on sale. LC-MS separates a sample into its parts and identifies each one by mass, so it confirms what the compound is and how much of the sample it makes up. The current batch tested at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
Storage and handling
Keep it in a cool, dry place away from direct sunlight. Leave packets sealed until you need them, and use each one once. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
